Regeneration of Phosphorous Saturated Activated Alumina

Enviro-Neptune致力于研究、开发和改进技术，致力于分散卫生设施的商业、机构和社区应用。当涉及到我们的水生环境时，磷酸盐的去除正在被研究，因为它对环境的影响很大。现代农业主要依赖磷矿中的磷，而磷矿是一种不可再生资源。有必要回收磷酸盐作为可持续粮食生产的资源。活性氧化铝（AA）是一种无机多孔材料，半结晶，主要由氧化铝组成，具有许多独特的特性，使其成为许多不同应用的良好候选者。lamton College和Enviro-Neptune的合作项目将侧重于了解饱和AA中P的解吸机制，确定饱和AA中P的解吸水平，并确定P的回收率。本研究的目的是评估一种更有效的解吸过程的潜力，在高浓度和低浓度的情况下再生磷饱和的AA，并确定这一有价值来源的回收率。这项研究的成功将导致这项新技术的整合，并将为Enviro-Neptune提供具有竞争力的价格优势，因为公司的运营和维护成本将会下降。此外，这将有助于避免每年约$128,000的废物管理和填埋费用。此外，用AA回收磷的任何贡献都将节省加拿大进口磷的资金，从而在经济上对加拿大有利。

Enviro-Neptune works in the research, development and improvement of technologies dedicated to commercial, institutional and community applications in decentralized sanitation. When it comes to our aquatic environments, phosphate removal is being investigated due to its significant environmental impact. The majority of our modern agriculture is mainly dependent on Phosphorus (P) derived from phosphate rock, which is a non-renewable resource. There is the necessity for recovery of phosphate as a resource for sustainable food production. Activated Alumina (AA) is an inorganic porous material, semi-crystalline and essentially comprised by aluminum oxide with a number of unique characteristics that make it a good candidate for many diverse applications.The proposed collaborative project Lambton College and Enviro-Neptune will focus on understanding the mechanisms of desorption of P in saturated AA, determining the level of desorption of P in saturated AA, and determining the percentage of recovery of P. Overall, the purpose of the present study is to evaluate the potential for a more effective desorption process to regenerate AA saturated in P for both high and low concentration scenarios and determine the percentage of recovery of this valuable source. The success of the research will lead to the integration of this new technology and will provide Enviro-Neptune with a competitive price advantage in the market since the company's operating and maintenance costs will drop. In addition, this will help to avoid waste management and landfill cost that it is approximately $128,000/year. Furthermore, any contributions with phosphorous recovered with AA will be economically beneficial for Canada by saving money on P imports.
